A New York Senate bill to extend the striped bass season by two weeks went belly-up after it failed to make it through an Assembly committee.

The Senate bill, which was approved in May, would have allowed fishermen to harvest striped bass until Dec. 31 of each year, adding another 16 days to the season.

Senator Ken LaValle (R-Port Jefferson) sponsored the bill, and initially proposed to have the season extended to Jan. 15 of each year.

The bill states that extending the season “will help create jobs, boost the Long Island economy, and ensure that quotas can be reached even if affected by natural causes.”

But the bill did not make it out of the state Assembly’s environmental conservation committee, government officials said.

William Young, president of the New York Coalition for Recreational Fishing, a preservation lobby, said the striped bass stock is in decline and that extending the season would threaten the fish.

His group sent letters to assemblymen and senators, urging them to let the bill die.

“The signs are that [the bass population] is not going in the right direction,” he said. “That’s up and down the coast, not just one area.”

A status update of the striped bass stock hasn’t been completed since 2011, said Mike Waine, a coordinator with the Atlantic States Marine Fisheries Commission, which helps to set fishing quotas for commercial operations to protect fish populations.

The commission will complete its latest assessment later this year and release the results in the fall, Mr. Waine said.

Mr. Young said it would be unwise to change fishing regulations without knowing the latest information on the striped bass stock.

“Right now is not the time to do it, there’s a question mark,” he said. “Right now is the time to wait and see what’s coming down the road.”

But Bonnie Brady, executive director of the Long Island Commercial Fishing Association, said the bill would have helped fishermen meet their quotas, even if stormy weather or other conditions prevented them from getting out to fish.

Life could get just a little easier for East End commercial fishermen if a bill Senator Kenneth LaValle (R-C-Port Jefferson) ushered through the New York State Senate has the same support in the Assembly.

The bill that passed the Senate with only a single negative vote would allow commercial fishermen to aggregate their daily catch limits over a seven-day period. A fisherman could, for example, catch three times his daily quota on Monday and two times the limit on Wednesday and then stay off the water until the following Monday, thereby conserving fuel. The bill that passed the Senate would also allow individuals, each of whom had a fishing license, to go out together in the same boat with each able to take a daily or aggregate limit.
